MECHANISM FOR RAISING SEWAGE.

Application filed October 19, 1926. Serial No. 1%,759.

This invention relates to a new and improved ejector device for sewage and other liquids containing considerable amounts of SUSpGIll'lBd matter, and it also relates to a 5 new and improved method for simultaneously raising both the liquid and solid portions of sewage.

One of the objects of this invention is to provide a device which will raise the suspended matters in the sewage and retain them adjacent the point of ejection.

Another object of this invention is to provide a device of this character which will be non-clogging and which will permit the removal of the accumulated solid 'matters from a point near the point of ejection.

Another object of this invention is to provide a simple and eficient device which will he free from moving parts.

Other objects of this invention will be set forth in the following description and drawing which illustrate a preferred embodiment of this invent-i011, it being understood that the above general statement of the objects of this invention is intended merely to generally explain the same and not to limit it in any manner.

Fig. 1 is a sectional View.

Fig. 2 isan elevation.

The device comprises a casing 15 con nected at the bottom thereof to a coupling member 21 having an externally threaded coupling member 22 which can be connected to the top of a flexible pipe, the bottom of which can be led into the sewer or the like. The top of the casing 15 is also provided with a coupling member 16, and this is connected to the flange 17 of a cover 10 by means of bolts 18 which have suitable nuts affixed thereto, as clearly shown in the drawings. The cover 10 is provided with an internal flange having a threaded opening and a dividing chamber 19 is connected to the internal flange of the cover 10 as clearly shown in Fig. 1. This chamber 19 consists essentially of a series of bars separated by longitudinal openings 20. The edges of these bars are formed with sharp cutting edges so that if any suspended matter is forced against such sharp cutting edges, said solid matter is cut up so that it enters the sediment chamber in relatively finely divided form. The cover 10 is also provided with an ejector inlet nozzle 13 and an ejector outlet nozzle 14 to which suitable pipe couplings 11 and 12 can be respectively connected.

In operating the device, water is forced through the inlet nozzle 13 with considerable velocity and passes out of the cover 10 through the outlet nozzle 14:. This rapidly moving stream of water which is thus forced through the cover 10 produces a lowering of the pressure at the side of the said the pump from clogging, it was necessary to provide a strainer at the bottom of the pipe, which was immersed in the sewer. Hence, after all the liquid sewage had been pumped out, the removal of the solid portion of the sewage involved additional unpleasant labor and expense.

According to this invention, the casing 15 is located above the street level, it may be laid flat upon its side, and the flexible pipe which is connected to the member 22 can be led upwardly from the casing 15 so that the solid matters which accumulate in the casing 15 cannot fall back into the sewer. The solid sewage is thus raised directly into the casing 15 above the street level. Those parts thereof which can be cut up by the sharp edges before mentioned, pass through the dividing chamber 19 and out of the cover 10, due to the action of the jet of water. The heavier and more solid matters accumulate in the casing 15, so that the said casing can be readily cleaned at or above the street level, whenever this is necessary. In fact, if desired, the casing 15 could be arranged in inverted position above the street level. 4

The chamber 19 has a bottom cap which is preferably imperforate.

For convenience, the cover 10 is specified as being at the top of the chamber or casing 15, but the use of the word top is not intended to limit the position in which the casing 15 can be placed.

A preferred embodiment of this invention has been shown, but it is clear that numerous changes and omissions could be made Without departing from its spirit.

Claims:

l. A sewer cleaning device having a casing adapted and intended to be located above the street level, said casing having an ejector at one end thereof, the other end of the said casing being adapted to be c0nnected to the sewer by a flexible connection, a chamber located Within the said casing and having'perforated Walls adapted to commi nuteinaterial passing through said perform tions, the top of said chamber being open and being adjacent the ejector.

2. A sewer cleaning, device having a easing adapted and intended to be located above the street level, said casing having an ejector at one end thereof, the other end of the said casing being adapted to be con- 1,713,791 W A v a nected to the sewer by a flexible connection, a chamber located Within the said casing and having perforated Walls, adapted to comminute. material passing through said perforations, the top of said chamber being open and being adjacent the ejector, the Walls of the said chamber consisting substantially of vertically spaced bars provided with cutting edges. y y a In testimony whereof We affix our signatures.
